Filed: 1975-03-21
Abstract: 1493522 Preparing tertiary (hydroxymethyl)- methyl-phosphine oxides HOECHST AG 21 March 1975 [22 March 1974] 11927/75 Heading C2P A tertiary phosphine oxide of the formula: R(CH 3 )P(O)CH 2 OH in which R is an optionally substituted alkyl, cycloalkyl, aralkyl or aryl group, other than a hydroxymethyl group, and having up to 18 carbon atoms is obtained by subjecting a tertiary phosphine of the formula: R.P(CH 2 OH) 2  to a thermal rearrangement reaction at above 90‹ C., e.g. from above 90‹ C. to 180‹ C., or in the presence of a catalyst comprising CCl 4 , CBr 4  or a Lewis acid at a temperature of - 10‹ C. to + 250‹ C. The reaction may be carried out in the presence of an inert solvent or diluent which may be a polar or non-polar solvent. In a modification of the process (hydroxymethyl) dimethyl phosphine oxide is prepared from primary methylphosphine by reacting the latter at atmospheric pressure and at below 40‹ C. with formaldehyde, paraformaldehyde or trioxane in the presence of an inert polar organic solvent to form bis-(hydroxymethyl) methyl phosphine and then subjecting the latter to the defined thermal rearrangement at above 90‹ C. or to rearrangement in the presence of one of the specified catalysts at a temperature in the range of - 10‹ and + 250‹ C. A suitable Lewis acid catalyst is BF 3  etherate. The rearrangement reaction is advantageously carried out under an inert gas such as nitrogen, CO 2  or argon and although it is preferred to use an inert solvent or diluent in the rearrangement reaction it may be carried out in the absence of a solvent in which case it is suitably effected in a thin layer evaporator, tubular reactor or packed column, e.g. in a column packed with metal powder, quartz sand, glass rings or balls.

Abstract: 233,726. Feldman-Patente Ges. May 8, 1924, [Convention date]. Pencil holders.-In pencil holders of the kind wherein the lead is projected by the relative longitudinal movement of inner and outer tubes, the inner and movable tube b, Fig. 1, is provided at its lower end with a sleeve member s terminating in a conical bore w which co-operates with a tweezer-like gripping-device comprising claws q at the ends of limbs p extending downwardly from a sleeve n which is freely displaceable upon the lead-guiding tube e, the arrangement being such that, in the writing position, a helical spring x forces the conical bore w into engagement with the gripping-claws, which are pressed into slits f in the lead-guiding tube to grip the lead. The limbs p of the lead grippers pass through guide slots m in a disc l at the lower end of a tubular stop k secured upon the leadguiding tube e, and the portions of the limbs below the stop k are bent outwardly at z, Fig. 3, to engage the wall 5 of the sleeve s and intensify the grip upon the lead when in the writing position. The lower end of the lead-guiding tube e is screwed into a tubular plug d which is also threaded to receive the pencil tip 6, and is thereby rigidly secured to the casing a. A plug g secured upon the upper end of the tube e forms the bottom of a magazine h at the upper end of the tube b, a conical recess being provided to guide the leads into the tube e. The tube b is attached to the sleeve s by a bayonet joint attachment near their lower ends. When the tube b is pushed within the tube a by applying pressure upon a cap c, the. sleeve n is carried forward by the frictional engagement of the claws g and the walls of the conical recess w, and the lead is projected until the slotted disc l on the stop k prevents further movement of the sleeve n carrying the claws. On continuing the pressure, the sleeve s is moved forward into contact with the upper end 2 of a tubular stop 3, as shown in Fig. 3, and during this further movement the resilient limbs p of the tweezers spring open. When the pressure upon the cap c is released, the sleeve s is pressed upwardly by the spring x, carrying the tweezers with it, the open claws q being engaged by shoulders 4 bounding the conical recess w. The tweezers continue to move until the upper end of the sleeve n is arrested by the plug g, after which the claws q are pressed inwardly and grip the lead in a new position on the return of the sleeve s and tube b to their normal writing position.
